Duggars' adoption possibilities could expand family

Jim Bob and Michelle Duggar tell People magazine they're considering adoption. The stars of TLC's "19 Kids and Counting" have 19 children, two grandchildren and a third on the way.

Michelle Duggar says the younger children are pushing their parents to bring another baby into the family. Whether they adopt or have another biological child, the Duggar parents say they will approach any changes with open hearts.
